How many outer ring electrons do calcium and oxygen have?
Calcium has 2 outer ring electrons, while oxygen has 6 outer ring electrons.
Would you expect calcium to gain or lose electrons in a chemical reactions?
Calcium is expected to lose electrons in a chemical reaction because it is a metal located in group 2 of the periodic table, which typically loses electrons to achieve a stable electron configuration. Calcium will typically form a 2+ cation by losing 2 electrons in reactions.
Why is calcium a good conductor?
Calcium is not a good conductor of electricity. In fact, it is a poor conductor of electricity because it has a full outer electron shell, making it difficult for electrons to move freely within the material. This lack of mobility of electrons restricts the flow of electric current through calcium.
What is the number of protons and neutrons in a calcium nucleus?
The atomic number of calcium is 20 and relative atomic mass (nucleon number) 40.1. The nucleon number is a decimal because it is an average value having taking all the different isotopes into consideration, based on their relative abundance. So all calcium atoms have 20 protons and 20 electrons. The number of neutrons will depend on what isotope of calcium we are talking about; calcium has 24 isotopes. If we consider the isotope calcium-40, which is the most abundant of all at about 97%, the can determine its number of neutrons as 40 - 20 = 20. So a calcium-40 isotope has 20 neutrons.
How many valence electrons are transferred from the calciun atom to iodine in the formation of the compound calcium iodine?
I believe you mean the formation of the compound calcium iodide. In the formation of calcium iodide, CaI2, the calcium atom transfers two valence electrons to two iodine atoms, with one electron going to each iodine atom. This causes the formation of a calcium ion, Ca2+, and two iodide ions, I-. The electrostatic attraction between the oppositely charged ions forms the ionic bonds that form the compound calcium iodide.
How many valence electron does calcium have?
Calcium has 2 valence electrons, like all Group 2 elements.
What is the charge of valence electrons of calcium?
The charge of valence electrons in calcium is +2. This is because calcium belongs to Group 2 of the periodic table, which means it has 2 valence electrons. Valence electrons are the outermost electrons in an atom that participate in bonding.
How many outer ring electrons do calcium and oxygen have?
Calcium has 2 outer ring electrons, while oxygen has 6 outer ring electrons.
How many unpaired electrons are in calcium?
There are no unpaired electrons in calcium, all 20 electrons are in pairs, i.e. each pair is configured in one orbital: 2x in 1s orbital 2x in 2s orbital 2x in each of the three 2p orbitals 2x in 3s orbital 2x in each of the three 3p orbitals and 2x in 4s orbital (these two are the valence electrons)
Would you expect calcium to gain or lose electrons in a chemical reactions?

What is calcium charge on the ion?
The metal calcium is an Alkaline Earth element, which is found in Group 2 of the Periodic Table. All the Group 2 elements have two valence electrons, and these elements want to loan them both out. This will leave a calcium ion with a +2 charge. Because calcium wants to loan out both its valence electrons, it will form compounds based on its desire to do so. Calcium will form bonds in a one-to-one ratio with elements that want to borrow 2 electrons, like oxygen. The compound will be calcium oxide, with CaO as its chemical formula. In the case of elements that want to borrow just one electron, like fluorine, chlorine or any of the halogens, the Group 17 elements, it will form bonds in a one-to-two ratio. Calcium fluoride, CaF2, and calcium chloride, CaCl2, are examples. A link can be found below.
What makes up calcium-40 ion with a charge of 2 plus?
Calcium-40 with a 2+ charge has lost two electrons, making it a Ca2+ ion. This ion contains 20 protons, as in all calcium atoms, and 18 electrons (since it lost two electrons).
How many outer-ring electrons do calcium and oxygen have?

Is calcium sulfide a ionic or covalent bond?
It has a Covalent bond 6 Electrons from the Sulphur atom are shared with the 2 electrons of the Calcium atm. It has a Covalent bond 6 Electrons from the Sulphur atom are shared with the 2 electrons of the Calcium atm.
What element is a metal with 2 valence electron?
All alkali earth metals have 2 valence electrons.
How many valence electron calcium atom has?
The first layer has two, since the maximum amount of electrons you may have in layer one are two, after the first layer you may have a maximum of eight electrons per layer, so layer one has two, layer two has eight, and layer 3 has a maximum of 18. To find the maximum number of electrons each layer can have do the equation 2(n2) n=number of layers
